Applications of Stainless Steel in the Pulp and Paper Industry

Steel Dynamics supplies stainless steel for various applications within the pulp and paper industry. Here are some key areas where stainless steel plays a vital role:

 

Pulping Equipment

The pulping process is a critical stage in paper manufacturing, and the equipment used must be robust enough to handle aggressive chemicals and high temperatures. Steel Dynamics supplies stainless steel for the construction of digester vessels, where wood chips are cooked with chemicals to produce pulp. The high temperatures and corrosive nature of the pulping process necessitate the use of stainless steel to ensure the longevity of these vessels.

 

In the refining stage, stainless steel pumps and valves are also used to transport pulp through various processes. The durability of stainless steel minimises the risk of failure, ensuring a smooth and efficient production process.

 

Paper Machines

Paper machines require components that can withstand high pressures, temperatures and exposure to water and chemicals. Stainless steel is essential for maintaining the integrity and performance of these machines. Steel Dynamics provides stainless steel for rolls and cylinders used in paper machines. These components must endure significant wear and tear while maintaining precise dimensions for optimal paper production.

 

In the drying section of paper machines, stainless steel is used for dryer cans. The excellent heat conductivity and corrosion resistance of stainless steel ensure efficient drying while minimising maintenance.

 

Chemical Recovery Systems

Chemical recovery systems play a crucial role in the pulp and paper industry by recycling chemicals used in the pulping process. Steel Dynamics supplies stainless steel components for evaporators and recovery boilers, which are essential for concentrating and recovering cooking chemicals. The high-pressure and corrosive environments require materials that can withstand significant stress and chemical attack.

 

In the black liquor evaporation process, stainless steel supplied by Steel Dynamics is utilised for piping and fittings that transport corrosive liquids. The durability of stainless steel ensures safe and efficient operation of these critical systems.

 

Storage Tanks

Storage tanks are essential for storing various materials, including chemicals and finished products. Stainless steel is commonly used in these applications due to its strength and corrosion resistance. Steel Dynamics supplies stainless steel for the tanks storing chemicals used in the pulping process. The resistance to corrosion ensures that these tanks maintain their structural integrity and prevent contamination of stored materials.

 

In the finished product storage area, stainless steel tanks are also used to store various types of paper products. The hygienic properties of stainless steel make it ideal for maintaining product quality.

 

Conveyor Systems

Conveyor systems are critical for transporting materials throughout the pulp and paper production process.

Steel Dynamics provides stainless steel components for conveyor belts used in the paper manufacturing process. These components must be robust and resistant to corrosion to ensure the efficient movement of materials.

 

In recycling operations, stainless steel is used in conveyor systems that handle recycled paper and pulp. The durability of stainless steel components minimises downtime and maintenance costs.
